"unless Google happens to be working at the height of early 90's tech" We are working at the height of 90s tech. For a consumer product, cheap enough to mass produce at a price people are willing to pay ($200-$600) you have to step backwards in time a bit for embedded system design. I've built a wearable using this type of display (the half inch micro display) and the biggest issue is that you cannot resolve an image well that close to your eye without giving you a instant eyestrain headache. You need a lens system to create virtual distance between your eye and the display. This is also the big issue with the "project the display on/in the lens approach." You need to have a focal length for the display similar to the depth at which the user spends most of their time looking, otherwise switching from real world to display and back is rather headache inducing. I'm really excited about this too, but more for main-stream attention on a field that has been marginalized for over 10 years now.

Wait, sorry, do you mean you (personally) or you (Google)? I'm aware of other microdisplay-based goggles like the Recon Instruments stuff - where a microdisplay approach makes more sense, but it's not covering your FOV. Have you worked with HOEs at all? Or worn these glasses? It's true that you need to place the image carefully, but, for example, in the case of the Lumus display it appears about 10 feet out from you, which was alright for me on the showroom floor. At CES 2012 Vuzix claimed they'd have $600 goggles in Q2 2013. This fall they are doing a monocle for $2500. No pricing at all from Lumus. Of course, I am appropriately skeptical about these claims, but HOEs are eminently manufacturable, pico projectors are cheap, and as you say, the renewed attention on this space is pretty rad. I'm optimistic. If the Google Device doesn't use the future looking stuff, I'll just buy the Vuzix set and develop on that.

  ok, pronoun breakdown because apparently I did poorly. We=Engineers in general I = Me personally you = potential designer of a wearable display, could be replaced with "one" If the displays work as well as you describe (I hope they do!) then they would be great for mass production in a product like this(a glasses based wearable) in 5-10 years or so when they are inexpensive.

    Yeah, especially since you are working in this space, you really, really need to see these. They're not 5-10 years off like they were 5-10 years ago.
